About Converting Hectoliters per Millisecond to Gallons per Millisecond
Hectoliter per Millisecond and Gallon per Millisecond both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallons per millisecond = hectoliters per millisecond × 26.4172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per millisecond equals 100 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct hectoliter per millisecond-to-gallon per millisecond factor of 26.4172052358.
Simple example
1 hL/ms × 26.41720524 = 26.41720524 gal/ms
1 hectoliter per millisecond = 26.41720524 gallons per millisecond.
Real-world example
60 hL/ms × 26.41720524 = 1,585.032314 gal/ms
60 hectoliters per millisecond = 1,585.032314 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 hectoliter per millisecond?
1 hectoliter per millisecond equals 26.41720524 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per millisecond to gallon per millisecond?
Multiply the hectoliter per millisecond value by 26.41720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to hectoliter per millisecond?
Use the reverse factor: 1 gallon per millisecond equals 0.0378541178 hectoliters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per millisecond?
Hectoliter per Millisecond (hL/ms) is a unit of flow rate.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the hectoliter per millisecond to gallon per millisecond conversion exact?
Yes. Both hectoliter per millisecond and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 26.41720524 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
